高寒地区引进体大高产澳血细毛种羊适应性观察

要组织一定区域内乃至全国范围内的联合育种,首先必须对不同区域的优良品种在联合育种区进行适应性观察试验,这是前提.为了增大甘肃高山细毛羊体格,提高羊毛产量,2008年甘肃省绵羊繁育技术推广站从内蒙古赤峰市南部的敖汉种羊场引进12只含澳血的体大高产公羊,我们对12只种羊进行了高寒地区适应性观察试验,通过试验得知含澳血的体大高产公羊能够完全适应祁连山高寒地区气候环境,其生产性能没有受到高寒气候的影响,该结论对导入体大高产澳血公羊增大甘肃高山细毛羊体格、提高羊毛产量提供了宝贵的理论依据.

Adaptive Observation of the Large High-yield Australian Blood Breeding Sheep from Cold Aarea

To organize the joint breed in a certain area and even the whole country, first of all, we must make the adaptive observation experiment for different varieties in joint breeding area. In order to increase the physique of Gansu fine- wool sheep and improve the production of wool , in 2008 ,Gansu sheep breeding technology extending stations bring 12 sheep from chifeng city of Inner Mongolia in the south of AoHan sheep farm. The ram contains Australia＇s blood. We had a high altitude observation adaptation to 12 breeding sheep. Through blood tests, we know that the large high-yield Australian blood breeding sheep completely adapt to the climate in Qilian mountain. Its production performance is not affected by cold weather. The conclusion provides valuable theoretical basis on ponderal growth and improving wool production with the Australia＇s blood.
